Description
Broan® Automatic Make-Up Air Damper, Universal, For Use With: 400 cfm Range Hood, 24 ga Steel, Galvanized, 9 in D
Features:
- Broan® interlocked make-up air dampers provide outside air when required to keep the air in the home fresher by allowing the range hood to operate at optimum levels
- Universal design works with any Broan® range hood to balance indoor air pressure by providing interlocked make-up air without requiring a direct wire connection between the range hood and the damper
- Instead a sensor is attached to the exhaust duct to detect if the range hood is operating
- Slave dampers (MD6S, MD8S or MD10S) are interlocked to the main automatic or universal make-up air damper and open in unison for synchronized operation
- They close, along with the main damper, as soon as the range hood is powered off, slave dampers can be "ganged" together to provide a cost effective means to provide for higher volumes of make-up air
- Interlocked make-up air damper systems meet IRC code requirements for make-up air with range hoods over 400 cfm
- Interlocked make-up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well-balanced environment
- Fresh air wall caps are required for use with make-up air dampers
- Also works with ULTRA and QT series fans if at least 80 cfm
